Created for comfort
Our patented Twist-O-Flex design was built to maximize comfort while creating a sleek, easy-to-wear design.
Absolutely loved it. Great quality, well made and definitely beats the one I bought from suppliers listed with Best Buy. My Speidel's strap fits the Fitbit just right not like my old one which keeps falling off.
I would have loved to keep this band, but I have an Inspire and they don't make a twist-o-flex for that one. That's the only reason I gave it a 3.
